.SH "DESCRIPTION"
.PP
\fBTspi_PcrComposite_SetPcrValue\fR sets the digest for a given PCR index inside the PCR composite object.
.SH "PARAMETERS"
.PP
.SS hPcrComposite
Handle of the PCR composite object instance where a PCR value should be set.
.PP
.SS ulPcrIndex
This parameter indicates the index of the PCR to set.
.PP
.SS ulPcrValueLength
The length (in bytes) of the rgbPcrValue parameter.
.PP
.SS rgbPcrValue
Pointer to memory containing the actual value which should be set for the PCR indicated by ulPcrIndex.
.SH "RETURN CODES"
.PP
\fBTspi_PcrComposite_SetPcrValue\fR returns TSS_SUCCESS on success, otherwise one of the following values are returned:
.TP
.SM TSS_E_INVALID_HANDLE - Either \fIhPcrComposite\fR or \fIulPcrIndex\fR is an invalid parameter.
.TP
.SM TSS_E_INTERNAL_ERROR - An error occurred internal to the TSS.
